To provide a vehicle rear part structure which can reduce the air resistance of a vehicle at appropriate timing.SOLUTION: A vehicle rear part structure 100 is provided on a vehicle rear surface 2 and includes an opening/closing mechanism 11 which switches between passage and shutdown of air from a blower mechanism 10 by opening/closing. The opening/closing mechanism 11 can switch between a state of blowing the air from the vehicle rear surface 2 and a state of stopping the air blowing by switching between the passage and the shutdown of the air from the blower mechanism 10. The opening/closing mechanism 11 opens when the vehicle 1 is at a speed equal to or greater than a prescribed speed. Therefore, the opening/closing mechanism 11 reduces negative pressure by blowing the air from the vehicle rear surface 2 at timing at which speed of the vehicle 1 is high and an eddy area is formed on the rear side of the vehicle. Also, the opening/closing mechanism 11 discharges the air after cooling to below the vehicle 1 by stopping the air blowing from the vehicle rear surface 2 so as not to blow against surrounding people such as passengers at timing at which the speed of the vehicle 1 is low or the vehicle is stopped.SELECTED DRAWING: Figure 2

    【課題】適切なタイミングで、車両の空気抵抗を低減することができる車両後部構造を提供する。【解決手段】車両後部構造100は、車両後面2に設けられ、開閉することによって、送風機構10からの風の通過と遮断とを切り替える開閉機構11を備える。この開閉機構11は、送風機構10からの風の通過と遮断を切り替えることで、車両後面2から送風する状態と、送風を停止する状態を切り替えることができる。そして、開閉機構11は、車両1が所定の速度以上の時に開く。そのため、開閉機構11は、車両1の速度が大きく、車両後方に渦領域が形成されているタイミングでは、車両後面2から送風することで負圧を低減する。また、開閉機構11は、車両1の速度が小さい場合や停止しているタイミングでは、乗客など、周囲の人に当たらないように車両後面2からの送風を停止して、車両1の下方へ冷却後の空気を排出する。【選択図】図2
